Substitute Part Grouping Explanation

Substitution of the Bourns 9210-66 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 62 µH with ±5% tolerance
• DC Resistance: 3.15Ohm maximum
• Current Rating: Minimum 160 mA (higher ratings are acceptable)
• Q Factor: 55 @ 2.5MHz
• Self Resonant Frequency: 11.5MHz
• Operating Temperature: -55°C to 105°C
• Package Type: Through-hole axial configuration
• Physical Dimensions: 0.156" Dia x 0.375" L (3.96mm x 9.53mm)
• Shielding Configuration: Unshielded

The API Delevan 1537-66J meets all substitution criteria with an enhanced current rating of 180 mA, providing additional design margin while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1537-66J is a direct functional equivalent to the Bourns 9210-66. Both components share identical electrical specifications for inductance, tolerance, DC resistance, Q factor, and self-resonant frequency. The substitute part offers a higher current rating of 180 mA compared to the original 160 mA specification, providing additional operational margin without compromising any other performance characteristics.

Both parts maintain identical physical dimensions and through-hole axial mounting configuration, ensuring mechanical compatibility in existing PCB layouts. The API Delevan part is currently in active production status, whereas the Bourns 9210-66 is obsolete, making the substitute the preferred choice for new designs and ongoing production support.

Compliance profiles are equivalent: both components are RoHS non-compliant and REACH unaffected, with matching ECCN and HTSUS classifications.
